Abstract

Apparatus for spreading a control signal comprised of widening circuits for extending the control signal horizontally and vertically, a line signal spreading circuit for generating a ramp of increasing values during a given interval at the beginning of each extended control signal, maintaining the maximum value of the ramp for the remainder of the extended control signals and generating a ramp of decreasing values at the end of each extended control signal and also including a circuit for combining the signal values at corresponding points along a plurality of lines as the lines are scanned.
